+Freescale MPC837xEMDS Board
+-----------------------------------------
+1. Board Switches and Jumpers
+1.0 There are four Dual-In-Line Packages(DIP) Switches on MPC837xEMDS board
+ For some reason, the HW designers describe the switch settings
+ in terms of 0 and 1, and then map that to physical switches where
+ the label "On" refers to logic 0 and "Off" is logic 1.
+
+ Switch bits are numbered 1 through, like, 4 6 8 or 10, but the
+ bits may contribute to signals that are numbered based at 0,
+ and some of those signals may be high-bit-number-0 too. Heed
+ well the names and labels and do not get confused.
+
+ "Off" == 1
+ "On" == 0
+
+ SW4[8] is the bit labeled 8 on Switch 4.
+ SW2[1:6] refers to bits labeled 1 through 6 in order on switch 2.
+ SW2[1:8]= 0000_0001 refers to bits labeled 1 through 7 is set as "On"
+ and bits labeled 8 is set as "Off".
+
+1.1 For the MPC837xEMDS Processor Board
+
+ First, make sure the board default setting is consistent with the
+ document shipped with your board. Then apply the following setting:
+ SW3[1-8]= 0011_0000 (BOOTSEQ, ROMLOC setting)
+ SW4[1-8]= 0000_0110 (core PLL setting)
+ SW5[1-8]= 1001_1000 (system PLL, boot up from low end of flash)
+ SW6[1-8]= 0000_1000 (HRCW is read from NOR FLASH)
+ SW7[1-8]= 0110_1101 (TSEC1/2 interface setting - RGMII)
+ J3 2-3, TSEC1 LVDD1 with 2.5V
+ J6 2-3, TSEC2 LVDD2 with 2.5V
+ J9 2-3, CLKIN from osc on board
+ J10 removed, CS0 connect to NOR flash; when mounted, CS0 connect to NAND
+ J11 removed, Hardware Reset Configuration Word load from FLASH(NOR or NAND)
+ mounted, HRCW load from BCSR.
+
+ on board Oscillator: 66M
+
+2. Memory Map
+
+2.1. The memory map should look pretty much like this:
+
+ 0x0000_0000 0x7fff_ffff DDR 2G
+ 0x8000_0000 0x8fff_ffff PCI MEM prefetch 256M
+ 0x9000_0000 0x9fff_ffff PCI MEM non-prefetch 256M
+ 0xc000_0000 0xdfff_ffff Empty 512M
+ 0xe000_0000 0xe00f_ffff Int Mem Reg Space 1M
+ 0xe010_0000 0xe02f_ffff Empty 2M
+ 0xe030_0000 0xe03f_ffff PCI IO 1M
+ 0xe040_0000 0xe05f_ffff Empty 2M
+ 0xe060_0000 0xe060_7fff NAND Flash 32K
+ 0xf400_0000 0xf7ff_ffff Empty 64M
+ 0xf800_0000 0xf800_7fff BCSR on CS1 32K
+ 0xfe00_0000 0xffff_ffff NOR Flash on CS0 32M
+
+3. Definitions
+
+3.1 Explanation of NEW definitions in:
+
+ include/configs/MPC837XEMDS.h
+
+ CONFIG_MPC83xx MPC83xx family for both MPC837x and MPC8360
+ CONFIG_MPC837x MPC837x specific
+ CONFIG_MPC837XEMDS MPC837XEMDS board specific
+
+4. Compilation
+
+ Assuming you're using BASH shell:
+
+ export CROSS_COMPILE=your-cross-compile-prefix
+ cd u-boot
+ make distclean
+ make MPC837XEMDS_config
+ make
+
+5. Downloading and Flashing Images
+
+5.0 Download over serial line using Kermit:
+
+ loadb
+ [Drop to kermit:
+ ^\c
+ send <u-boot-bin-image>
+ c
+ ]
+
+
+ Or via tftp:
+
+ tftp 40000 u-boot.bin
+
+5.1 Reflash U-boot Image using U-boot
+
+ tftp 40000 u-boot.bin
+ protect off fe000000 fe1fffff
+ erase fe000000 fe1fffff
+
+ cp.b 40000 fe000000 xxxx
+
+You have to supply the correct byte count with 'xxxx' from the TFTP result log.
+
+6. Notes
+ 1) The console baudrate for MPC837XEMDS is 115200bps.
